Maintaining Your Phone
When your phone is unable to operate properly, you need to investigate or troubleshoot issues
among other tasks your administrator may ask you to perform. This chapter explains how to
perform maintenance tasks on your phone:
 Diagnosing the Network
 Rebooting Your Phone
 Resetting to Factory Settings
 Updating the Phone Configuration
 Export All Diagnostic Files
Diagnosing the Network
The wrong network settings may result in inaccessibility of your phone and poor network
performance. In this case, your system administrator may ask you to use the “Ping” or “Trace
Route” method to check whether the network is connected, and to analyze the network fault.
Checking the Network Using “Ping” Method
Procedure:
1. Navigate to Menu->Features->Diagnostics->Network->Ping.
2. Enter the desired IP address or URL in the Ping IP or URL field.
3. Press Start.
The screen displays the network status information.
4. Press Back to back to the preview screen.
